Corn: Sowing Parameters

Aim. To highlight the results of research conducted in 2020 – 2021 aiming at studying ffect multi-depth and multifraction sowing hybrid corn seeds DMS Sticker mid-early maturity group on yield when grown conditions Northern Steppe Ukraine determine economic efficiency approaches.Materials methods. Winter wheat was a predecessor crop study. Tillage methods related are described article. Herbicides were used to protect against weeds. Sowing carried out third decade April soil temperature +8 10 ºС. The experiment considered 2 factors, namely depth size seed fraction. obtained processed using measurement, mathematical statistical research, as well calculation comparison approaches.Results discussion. On average, depending factors studied, height plants varied significantly, rule, tallest from large seeds, which had highest mass 1000 seeds. Thus, particular, average over two years 250.4 cm weight 255 g, wrapped by 4 5 cm; 300 251.1 cm, while with 350 g it 258.3 wrapping 7 8 252.1 255.8 268.5 11 257.6 261.8 266.1 cm.Conclusions. use fraction provided an increase 1.09 1.79 t ha-1 compared small 8.70 ha-1. When cost production 56,550 UAH price 1 ton lowest amounted 2,247.1, conditional net profit 37,000 ha-1, level profitability 189.3 %.
